　　织梦dede:arclist按最新修改排序orderby=pubdate无效的解决方法

　　打开 /include/taglib/arclist.lib.php 找到

　　else if($orderby == 'sortrank' || $orderby=='pubdate') $ordersql = " ORDER BY arc.sortrank $orderWay";

　　改成

　　else if($orderby == 'sortrank') $ordersql = " ORDER BY arc.sortrank $orderWay";else if($orderby == 'pubdate') $ordersql = " ORDER BY arc.pubdate $orderWay";
